What is the best service to rent a car in Portugal?

A couple of months ago I traveled around the south of Portugal — the Algarve region. It's really hard there without a car: the beaches are scattered, buses are rare. I used the https://roscar.pt/ website. At first I was skeptical, but everything went great — the price was normal, and the car was in good condition. If you're in those parts, it's really convenient to rent through them.
